PROBLEM TO BE SOLVED: To provide a washing water tank for flushing hot water only from a flush port to actualize comfortable washing while suppressing the mixing of hot water with cold water by uniformly supplying washing water from the bottom of the washing water tank. SOLUTION: The washing water tank comprises a straightening means 35 for regulating the flowing condition of washing water provided in the inside of an entry port 27, the straightening means 35 having a deflection part 38 for deflecting the flowing direction toward the bottom face, a regulating part 40 for reducing a flowing speed into a uniform flowing speed, and a flow-out part 42 for making the washing water flow out along the bottom face of a tank body. When the speed of the washing water flowing into the tank body 22 is lower, the speed of the washing water flowing in the regulating part 40 is uniform, and so hot water is almost never mixed with cold water. Thus, only the hot water having an optimum temperature flows out of the flush port 28 provided in the upper part to actualize comfortable washing. COPYRIGHT: (C)2008,JPO&INPIT
